CDSView with CNPJ from Company Code - Brazil

Hi all!

I need to create a new CDSView with informations about CNPJ Company Code. There is a function to calculate the CNPJ code in SAP ECC = J_1BBUILD_CGC. What I must do?

The CDSView "I_Branch" is not release and I can´t use to Associate Data Sources.

Best Regards,

José Hélder
